To all whom it may concern:

Be it known that 1,.Gnonon M. Wnnnnn, of the city of New York, borough of Brooklyn, county of Kings, and State of New York, have. inventedcertain new and use ful Improvements in Devices for Joining Parts of Conduits, the following being a full, clear, and exact specification of the improvements, reference being had to the accompanying drawings, where1n- Figure l is form ng 2 and 3 an elevation of the flange part of my improved device; are similar views, and Figs. 4: end an intermediate and of an end-link respectively, composing such a flange as shown in Fig. 1; Fig. 6 is an elevation of two sections of conduit held together by a device constructed according to my invention; Fig. 7 is a sectional view thereof, on line 77 indicated in F 6;.Fig. 8 an elevation of a movable flange to he nsed in connection with a compressible packing and Fig. 9 is a sectional view of a joint as is made to repair, temporarily, a. broken conduit, by means of my improved device.

Fig. 10 is another form of two sections of a conduit held together by means oi my invention. Fig. 11 is a sectional view of Fig. 10. Fig. 12 is e sectional view taken through the lineat the left of Fig. '10. Fig. 13is another view of the movable flange.

My improvement relates to devices employed in constructing re wiring and cleaning of vvaten, gas, steamand other hollow conduits and consists of devising the parts and their combinations for connecting and securing together sections and parts or" such conduits.

The flange shown in elevation in Fig. l

l is What ll term the stationary flange to distinguish it from the flange shown in. Fig. 8, which I designate as the movable flange. The stationary flange is composed of a series of links 1, shown independently in Figs. .2 and 4- in elevation and in plan view and hereafter. referred to as theiintermedinto links, and of tWo end lin s, designated by numeral 2 in the dravvin s. One such end link is shown independently in Figs. 3 and 5, in elevation and plan View. The

intermediate links 1 have both ends recessed and perforated, to enable them to he hinged together by bolts. The end-links 2 have each one end fitted to hinge with the-intermediate formed into a transverse flange 3, provided with a. bore 4- for inserting therein a screW-v bolt 5 to secure the. flange upon the conduit Where my improved device is used. The links of both kinds are arched to conform, approximately, to the circumference of a conduit; it is, however, not necessary that they should fit exactly. One great adventsge of composing the flanges of such links, lies in the fact, that it facilitates the coilstrnction of such flanges of almost any size of units easily packed or carried and readily put together as required.

The number of the intermediate links 1 to be used, is determined by their size and the size of the conduit Whereon the flange is to he aiiixed, but there must always be used two end-links 2, as otherwise the flange could not be rigidly secured to the conduit. Each of the links is provided with 2. lug 6, which is set approximately midway between its ends and projects diagonally from, and approximctety at right angles to, theconduit when the flange is eflixcd thereto. These lugs are slotted, the slots 7 serving for inserting therein of the stay-bolts 8. The stay-bolts serve, jointly with the flanges, for holding together of the parts of the conduit, as shown in Figs. 6 and 9. These stay-bolts are correspondingly long, screw-threaded rods, and screw-nuts 9 are fitted thereon to he screwed on. their ends when the device is put in position. These slots 7 may be open, as shown in Figs. 1 to 5, or closed, as shown in Fig. 8. The advantage of making the slots open, that the stay holts 8 may he slid in more rapidly, not requiring the nuts 9 to be removed therefrom. The advantage of having the slots 7 closed, as shown in Figs. 7 and 8, is that they retain the stay-bolts more securely when for any reason the flanges cannot be set exactly at right angle to the axis of the conduit, as it sometimes happens. W'hen flanges with closed slots are used, one of the nuts 9 is re Y., ASSIGNOR TO NATIONAL WATER. MAIN N. Y., A CORPORATION OF MAINE.

moved from each stay-bolt, to enable the same to be inserted therein.

The use of a device constructed according to my invention is shown. in Figs. 6 and 7 applied for holding together of two parts of a conduit, as'it is required. when laying or repairing such conduit or when such con= duit is shifted. In this form the device consistsof two such- (stationary) flanges as links their otner end is otlset and 1 shown in, .Eig. v1, and of a corresponding number of stay-bolts 8. The drawing shows the joint of two sections of a conduit pipe, the spigot-end ofthe section a being insorted in the bell-end of the section b. To secure the joint of the two sections, one such stationary flange'as shown in Fig. 1 is applied to each section of the conduit pipe .and affixed thereon rigidly by the bolt 5,

drawing together the flanges 3 of the and links 2. These flanges, designated and 0' in Fig. 6, are set in such position relatively to each other as to bring the lugs 6 thereof in anapproximate alinement, so the stay bolts 8, inserted therein, lie approximate y parallel to the line or axis of the conduit. Then the screw-nuts 9 on the stay-bolts are screwed on tight. It is not necessary to use more than four or five of such stay-bolts and three will be found suflicient for mostpurposes; but no lessthan three should be used and the stay-bolts should be always dis tributed, soas to be approximately equidistant from each other. This device holds .the sections of the pipes safely in alinement with each other and facilitates he ir setting and adjusting. It is also very handy and useful for holding the sections together while the packing or filling oftheir joints is done, and for other purposes.

When' the conduit is'broken, as it sometimes happens in excavations, or when a section thereof must be taken out, it is often necessary to insert a temporary connection. -For this purpose .heretofore expenslve solinks 1 shown in Fig. 2, and fitted to be hinged together by bolts. Some of'these links 12, two or more, asmay be, are provided with slots 11 in, place of the round bores 10 for oining the links together and around the section f of the conduit. The

' object of this' arrangement is to make this flan e fit loosely around the section of the conduit and to enable it to be drawn by screwing on the nuts 9 on the end of the stay-bolts projecting beyond the otherside of the fixed flange a, set on the bell-end of the section 0, serving as the temporary substitute of the broken part of the conduit.

.The packing 13 (see Fig. 9) is made of a suitably shaped packing material, preferably twilled rubber gasket or the like, cut to fit around the sections to be joined, and must be, of course, sufficiently dimensioned tionary flange 0 andthe end of the broken. conduit adjoining the packing ring 13, set V in the space between the interior of the section a and the exterior of the section f..

Then stay-bolts 8 are inserted in the lugs of all three flanges and the screw-nuts on their ends screwed on to hold'the sections 1: and f relatively to each other. Then the screw-nuts 14, set on the stay-bolts beyond the movable flange d, and the screw-nuts on their ends beyond the stationary flange secured to sect-ion e, are screwed on to press the packing 13 (by moving the flange all into the space between the interior of the section 0 and the exterior of section f, t()- make the joint tight. \Vhen that is done, the screw-nuts 9 on the stay-bolts 8 beyond the other fixed flange, secured to section f, may be screwed on more tightly to hold the joint more rigidly together, if necessary. The joint on the other end of the temporary section 8 must, of course, be made in the same manner.

- In many instances it will not be necessary to use the fixed flange on the ends of the broken conduit. This will often be the case a to support the temporary connecting section otherwise.

\Vhen only one stationary flange 1s used, it is affixed upon the section to be inserted in the conduit and the movbroken conduit. Then when the packing is put in place, the bolts are inserted in the slots of the flanges and by screwing on the nuts on their ends the packing is pressed into the space between the interior of the section jolning the broken ends and their exterior circumference.

This improved device, constructed according to my invention, permits the using for such purposes of almost any piece of pipe as may be handy at the site. As shown in Fig. 9 of the drawings, the section 6 representing such chance section found for repairing the break, is of'considerably larger diameter than the section f of the conduit.

It is advantageous to use for such temporary able flange is set on the endsection of the serve for such temporary repairs and exyoint, a section of pipe of larger diameter,

, diameter than the ecause the capacity of the conduit'is thereby not diminished. In cases of'emergency, however, if no section of pipe, larger in conduit, should be on hand, a section of pipe of smaller diameter 5 could be used to connectthe ends for such temporary repair of the conduit with my improved device; Such a connecting section would be slid into instead of over the broken ends of the conduit and the arrangement of the packing, the movable and the stationary flange would be reversed. By the combination of the proved device as hereinbe such material as is almost hand for ordinary purposes,

arts of my imore explained, invariably on may be made to pedients, for which heretofore only special fittings corresponding in size to the conduits, and particular implements had to be employed, and which, of course, are not and cannot well be, carried 'on hand, to have ready for such emergencies.
